11 Claims. (Cl. 138-465) exhaust pipe and having as one of their functions the deflecting of hot gases of combustion away from external painted and bright metal surfaces.

The object of the invention is to simplify the construction as well as the means and mode of fabrication of exhaust pipe extensions, whereby such extensions may not only be economically manufactured, but will be more satisfactory in use, of longer life, adaptable to a wide variety of applications, and be unlikely to get out of repair.

An object of the invention is to present a generally new device of the kind described having a large orna mental area without sacrifice of deflecting area,

A further object is to provide an extension device of new configuration in which the working deflecting surfaces are substantially concealed.

Another object of the invention is to make the instal lation and removal of the extension a considerably more facile operation than heretofore.

A further object is to make the device adjustable for selective enlarging of the neck portion thereof.

A further object of the invention is to present a fabricated extension device including means serving a dual purpose of interconnecting the parts and of providing a pivot for relative adjustment of the parts.

Still another object of the invention is to make use of substantially concealed deflector means contained within an adjustable outer shell and adjustable in correspondence with the outer shell.

A still further object of the invention is to achieve the foregoing advantages of ornamentation and facilitated installation and removal while retaining simplicity and economical construction.

A further object of the invention is to provide an exhaust pipe extension possessing the advantageous structural features, the inherent meritorious characteristics and the mode of assembly herein mentioned.

With the above primary and other incidental objects in view as will more fully appear in, the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, as hereinafter described or illustrated in the accompanying drawings, or their equivalents.

Referring to the accompanying drawing, wherein is found one but obviously not necessarily the only form of embodiment of the invention,

2,868,228 hatentoti Jan. 13, 1959 Fig. 5 is a View similar to Fig. 1, showing the shell elements adjusted, as preparatory to being positioned on an exhaust pipe.

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawing, an exhaust pipe extension in accordance with the illustrative embodiment of the invention is a fabricated device including a pair of similarly constructed superposed shell elements 11 and 12. The elements 11 and 12 have a generally triangular formation and are disposed in a mating relation to one another. The side edges of each are turned over into relatively interfitting relation in a manner to hold the body portions of the shell elements in approximately parallel, spaced apart relation.

Transverse means in the form of studs or rivets 13 and 14 are passed through the interfittingside edges of the shell'elements 11 and 12, interconnecting such elements and also providing a pivot about which the shell elements may be adjusted relatively to one another.

The shell elements 11 and 12, as interconnected by the means 13 and 14, comprise a shell assembly having a broad base portion 15, and, at its opposite end, a relatively constricted neck portion 16. The bodies of the shell elements are expanded so as to complementarily define a circular formation.

pipe so that the exhaust gases are discharged into the interior of the shell assembly toward the base 15.

The extension device when in use is remov'ably clamped to the exhaust pipe. In this regard clamp portions 17 and 18 project from the respective shell elements 11 and The extension device is of relatively flat, compactconstruction and the neck portion 16 and clamp portions 17 and 1% are arranged for a close contact with the exhaust pipe. ing directly in the shell assembly and not in the clamping portions 17 and 18 alone. For simplified installation and removal of the device, the shell elements 11 and 12 are rocked about the transverse pivot means 13-44, as for example to the position shown in Fig. 5. in the course of such motion the shell parts making up the neck portion 16, and the clamp portions 17 and 18 are moved in relatively separating directions increasing the size of the opening at the neck portion for a more facile reception of the exhaust pipe in the shell assembly or removal of the assembly therefrom.

While the extension device may function adequately as above described, with exhaust gases issuing from the rectangular opening at the base 15, the invention is further characterized by use of an auxiliary deflector element 21. The element 21 has a curved, trough-like formation.

posite end of the deflector element is curved in a compound manner and rests on the shell element 11 outwardly of the opening 22, and is thus in effect closed.

The upper curved wall of the deflector element substanside margins of the shell elements to define passages 23 and 24 through which air flowing in adjacent exterior relation to the exhaust pipe may pass through the shell assembly.

This formation, as will be understood, is positionable about the end of an exhaust The exhaust pipe is received.

Thus the pipe has a relatively long bearl ases,

The aforementioned outer or closed end of the deflector element 21 terminates in a flange 25 seated on the shell element Ill and connected thereto by a rivet 26 or the like. The rivet 2d loosely connects the deflector element to the shell element ll so that the deflector element may be tilted or raised and lowered relatively to the shell element.

According to this construction, therefore, when the shell elements 11 and 12 are pivoted apart as in Fig. 5, preparatory to being mounted on an exhaust pipe, the deflector element 21, being loosely connected to the inner surface of element 11, is adjusted in the direction of the upper shell element 12. The exhaust pipe is thus received between the curved upper wall of element 21 and the opposing wall of shell element 11, as the elements are mounted about the pipe so that the exhaust entering deflector'element 21 will be directed thereby for discharge by way of the opening 22.

The deflector element 21 may be made of any suitable corrosion resistant material, and, as noted, is substantially concealed within the shell assembly which may be plated or finished over its entire external surface with a bright metal.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously issueceptible of modification in its form, proportions detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the inven tion has been described in language more or less specific as to structural features, it is to be understood that the invention is not limitedvto the specific features shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into effect. 7
